Zero Gravity Chair Replacement Bungee Cords - 4-Pack Nylon Stretch Elastic Laces for Antigravity, Patio & Lawn Chair Repair - Durable Outdoor Lounge Chair Accessories for Relaxation & Backyard Comfort

First, let me say that restringing this chair is a total pain -- from removing the old lace to installing the new one. I ended up just cutting the old lace in several places since it was already stretched, rotted, and broken in some places. Secondly, it's going to take some time. And lastly, yes, the cords are long enough to complete the project -- both sets (shorter ones for the top half of the chair and longer ones for the bottom half of the chair). Understand that the zero gravity chairs use the tensioning of the laces to keep the webbed laying mat in place. The lacing *has* to be tight to keep the mat in place *and* to support the weight of the person sitting on it. There is some "give" to the string so that it has the ability to flex somewhat when a heavier individual sits on it. That's how they are designed.When I first started restringing my chair, I made the mistake of trying to pull both ends of the cord through the holes at the same time. Not only was this extremely hard to do, but it seriously hurt my hands. Instead, I looped the cord through the first "buckle" and then pulled each half of the lace through the holes one at a time. Doing it this way, I didn't need to use wire ties or binder clips to hold it, although that might really be helpful for some -- especially if you struggle with hand strength (and you will need a good amount of hand strength for this). Thank you to those who suggested these tips because you do need to keep the rope taught as you pull it through the holes. If you're working your way through the project and it comes up short, the most likely reason is because it wasn't pulled tightly enough through the buckles and the holes and not because they are sized wrong. I had to restring two strands due to not pulling it tight enough. The strength of these is pretty remarkable and like some of the others, I found it to be stronger than those that originally came with my chairs. Like all things left outside, I'm sure these will dry rot after time like the originals, but I'd definitely purchase these again as they are a good price and pretty easy to do once you get the hang of it. Just make sure you're pulling the cord tightly as you weave through. If you have an inch or so left after your last hole, it's much easier to end the cord and loosen it a little working backward through the lace than it is to re-weave it because it wasn't tight enough to start with.Remember -- Keep the lace as tight as you can moving up the chair through the buckles and laces. Good luck!!
